Abstract
Sublethal topically applied doses of the carbamate insecticide carbaryl and injection of certain s-triazine chemosterilants to female Diparopsis castanea Hmps. enhanced the rate of oviposition without reducing fertility. Treatment of male moths with carbaryl and certain s-triazines often caused an increase in mating disfunction expressed as an absence of sperm from the spermatheca after an apparently normal mating, permanent copulation or spontaneous extrusion of a spermatophore. No evidencewas found for a direct sterilising action of the chemosterilants against the insect sperm.
